Actuators & Sensors
Unitree M107 high-torque joint motors with field-serviceable modular design.
Force-torque sensing at key joints for whole-body control.
3D LiDAR + depth cameras + IMU for balance and perception.
Supply-Chain Analysis
Core joint motors and drive units are self-developed by Unitree.
Key reducer components sourced from domestic Chinese suppliers including Leaderdrive (Green Harmonic).
Battery and compute follow consumer-electronics cost discipline — the core of G1's pricing advantage.
Competitor Comparison
Compared with Tesla Optimus and Figure-01, Unitree G1 focuses on cost, agility and research-friendly openness rather than full-size factory automation. It competes with Kepler K2 and EngineAI's smaller models at the budget end of the market.
